@dannydr, I think you'll be interested in joining this discussion:
- Mayo new policy to charge for some patient portal messages
https://connect.mayoclinic.org/discussion/mayo-new-policy-for-charging-for-some-portal-message/ .

It's important to clarify that not all patient portal messages are subject to billing. To be eligible for billing, the message must be patient-initiated and require a clinical decision that otherwise would have been provided through an in-person or virtual office visit. Patients who can't afford the charges will be referred to financial assistance.

Have you received a charge for using the patient portal?
